High-quality unboxing photos of Apple's fourth-gen iPod nano

The new fourth generation Nano is Apple's thinnest iPod yet, but still delivers the same high resolution display of last year's wider, square model. It introduces Genius playlist creation on the go, audio recording features when used with a mic, and an accelerometer that enables "shake to shuffle" and automatic landscape reorientation with Cover Flow.

The new Nano ships with standard headphones; Apple will release two headphone options next month that include a mic and playback/volume controls: a standard earbud pair for $29 and a premium dual driver, in ear set for $79.
